After importing the xar for XEM 1.2M2 into an empty mysql database (per http://manager.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMySQL) I am experiencing some odd behavior. I can register as a new user, however, when trying to re-login as the user, no indication is given that the login was successful. ( I can¹t get to any Œedit¹ menus, etc...) This also applies for Admin/admin ... I don¹t get a login failure ­ but I don¹t get a change in the panels either. I did have some trouble getting the import to work (separate issue) - but it did eventually succeed ­ or so it seemed. What¹s the best way to Œreset¹ the database (or otherwise overcome this failure)?
